Vaccine Efficacy Denial: A Growing Concern Affecting Modern Science, and Impacting Public Health.

The discovery of the vaccination technique was revealed by Edward Jenner in 1796, which represented the first scientific attempt to control an infectious disease by vaccines, followed by other important studies carried out by Pasteur and Koch, and Sabin, who developed the first technique to attenuate the virus. In recent decades, numerous scholars have begun to create dangerous theories against the effectiveness of vaccines through scientifically invalid or fraudulent studies. This critical review of the literature aims to analyze the main factors that have undermined the credibility of vaccines in the general population, disproved false information and emphasized the benefits of vaccines over the last 200 years.

Comparison between Early Loaded Single Implants with Internal Conical Connection or Implants with Transmucosal Neck Design: A Non-Randomized Controlled Trial with 1-Year Clinical, Aesthetics, and Radiographic Evaluation.

Enrolled patients received bone level, 12° conical connection implants (Nobel Parallel, Nobel Biocare; NOBEL group) with anodized surface (TiUnite) and roughness of 1.35 μm, or transmucosal implant system (Prama, Sweden and Martina; PRAMA group) with convergent collar, ZIrTi surface, and roughness 1.

Healthcare Management During A Pandemic: The Other Side of the Coin for the Treatment of COVID-19 Infection.

Background: World Health Organization (WHO) has increasingly improved the guidelines to tackle the spread of Coronavirus Disease 2019 (COVID-19) among the worldwide population. In this context, each country has introduced specific social, healthcare, political and macroeconomic measures to face COVID pandemic locally.

Objective: The general aim of this comparative overview is to highlight the most significant effects of COVID-19 pandemic on the main healthcare systems.

New Generation of Fixture-Abutment Connection Combining Soft Tissue Design and Vertical Screw-Retained Restoration: 1-Year Clinical, Aesthetics and Radiographic Preliminary Evaluation.

Implant design factors and the abutment connection are correlated with crestal bone stability. The aim of the present study was to evaluate a new type of screw-retained prostheses delivered on tissue-level implants with conical external vertical seal and internal hexagon connection. Implants 4.

Transgingival implants with a convergent collar (PRAMA); surgical and screwed prosthetic approach. A case report.

This article presents a case report of transmucosal implant with a convergent collar (PRAMA) inserted in the anterior maxillary esthetic area. The purpose of this study is to evaluate soft and hard tissue after 12 months. One implant was placed in the esthetic area.

Convergent implant transmucosal collar and healing abutment: aesthetics influence on soft tissues. A clinical study.

Two conditions are necessary for a correct and functional prosthetic implant rehabilitation: maintaining pre-implant soft tissue health and stability of bone tissue, in terms of implant osseous-integration and maintenance of optimal crestal attachment levels. In addition to these parameters - necessary for the longevity of the restoration - one of the main aspects of therapy is the achievement of a final aesthetic that reproduces as faithfully as possible the natural anatomy of the lost tooth and the associated soft tissues. To achieve this last objective, an implant system was designed and used by our group.

Effectiveness of Ball Attachment Systems in Implant Retained- and Supported-Overdentures: A Three- to Five-Year Retrospective Examination.

Purpose: To evaluate implant and prosthetic survival rates, complications, patient satisfaction, and biological outcomes of patients rehabilitated with a ball attachment system for implant retained- and supported-overdentures (IOV), which was in function for 3 to 5 years.

Methods: This retrospective study evaluated data collected from patients treated between April 2001 and May 2018 with IOV on splinted and non-splinted implants and a ball attachment system. Patients were followed for 36 to 206 months (mean follow-up was 128.

Effect of Simultaneous Immediate Implant Placement and Guided Bone Reconstruction with Ultra-Fine Titanium Mesh Membranes on Radiographic and Clinical Parameters after 18 Months of Loading.

Background: The aim of the present prospective case series study was to evaluate the implant and prosthetic survival rates, complications and marginal bone loss using ultra-fine titanium mesh membrane with simultaneous implant placement, to provide space maintenance mandatory for guided bone reconstruction of alveolar bone defects.

Materials And Methods: patients were recruited and treated at a private clinic in Rome, Italy, between March 2016 and October 2017. Self-tapping tapered implants were placed through a computer-guided template-assisted approach.

Implant-abutment connections on single crowns: a systematic review.

Different implant-abutment connections have been developed in the effort of reducing mechanical and biological failure. The most frequent complications are screw loosening, abutment or implant fracture and marginal bone loss due to overload and bacterial micro-leakage. Ideal connection should work as a one-piece implant avoiding the formation of a micro-gap at the implant-abutment interface.

Maxillo-facial prosthesis (P.M.F): in a case of oral-nasal communication post-surgery and post-radiotherapy.

In patients with oral-nasal communication the absence of alveolar and/or palatal hard and soft tissue, or contraction resulting from previous surgical repair, needed prosthetic rehabilitation. This clinical report describes a treatment of an oral-nasal communication through a mixed prosthetic rehabilitation, fixed and removable, with attachments performed by EDM technique.

Esthetic and function rehabilitation of severely worn dentition with prosthetic-restorative approach and VDO increase. Case report.

Objective: The aim of this study is to report a case of restorative treatment of severely worn dentition. In this case report, the erosive/abrasive worn dentition have been reconstructed with metal ceramic crown on the posterior teeth and with ceramic veneers on the anterior teeth 1.3 - 2.

Full-arch maxillary rehabilitation fixed on 6 implants.

Objective: The purpose of this study is to report a case of full-arch rehabilitation on six endosseous implants loaded following the standard procedure.

Methods: An implant-prosthetic treatment was proposed to a 53-year-old woman with a total prosthesis in the upper jaw. Six implants on upper maxillary were placed keeping the upper complete denture during the osseointegration period.
